摘　　要：研究了Ｃｒ１２钢贝氏体含量与马氏体－贝氏体复相组织力学性能关系和工艺参数对强韧性的影响。结果表明，经低温回火，马氏体－贝氏体复相组织中含１５％～２５％下贝氏体时，钢的强韧性及模具使用寿命显著提高。The relationship between content of bainite in Cr12 steel and machanical property with (M+B) duel phase structure,and the effect of technical parameters on its strengthening and toughening was investigated.The result shows that in case of bainite content of (M+B)duel phase structure was about 15%～25% the strengthening and toughening and the service life of die is markedly increased.
